I thought I had a picture of this place in operation, but find I can't put my hands on it now.

This Richland Mall storefront is the old Eckerd's location, and I believe that up until the time Posh Pets grooming moved in, it had been vacant since the closing of that store. I am also pretty sure that for some reason, while it was Posh Pets the location had no interior signage or mall access.

I believe that Posh was only here for a year or two and has sinced moved out to Fort Jackson Boulevard and Sparkleberry.

UPDATE 11 November 2014 -- Here are those pictures I was looking for with the place in operation:

The Carolina's restaurant building at the Gervais Street Clarion is being razed as part of the upfitting of the property to become a dual branded Hilton Garden Inn / Home 2 Suites.

I never went there though over the years I heard it advertised many times, especially with New Years Eve packages at the hotel. I'm not sure exactly where the fancy spiral staircase fit in, but it doesn't seem like the sort of thing you would usually find in a hotel restaurant.

The State notes that the hotel was Sherman's Columbia headquarters and is a historic site. I confess I'm a bit confused about exactly what part of the property dates back that far. Surely the actual hotel building on Gervais is not that old.

UPDATE 4 November 2014 -- I had originaly titled this post Carolina's Restaurant, but according to the comments, that restaurant is still in service as part of the hotel proper:

The restaurant itself is still open. It closed temporarily during the construction, and then re-opened. The images that you've posted above were not the actual Carolina's Restaurant. That's actually inside the Clarion Hotel. That building was for banquet halls, conventions, and that sort of thing.

Checking my phonebooks, I see that Advance On Checks goes back at least to 2005, which really surprised me as I had not noticed in all that time that Hursey's Trading Post was gone. I never stopped in there, but I remember the signs that cheerfully promised loans on any item "except guns".

The real estate listing says this little building at the southwest corner of Two Notch & Beltline dates back to 1960, and looking at it, I can believe that. I also believe it must have been some sort of restaurnat at one time, but I have absolutely no memory of what it might have been.

A new apartment complex is coming to a premier setting on Cayce’s riverfront.

Plans for a complex of about 230 units near the Blossom Street bridge have received initial approval from Cayce City Council.

The site provides a prime view both of the Congaree River and the skyline of downtown Columbia to the east.

The project would extend along Knox Abbott Drive from Axtell Drive to the city’s Riverwalk, replacing Monterrey Mexican Restaurant and the Riverside Inn, which are across the street from Guignard Park.

Monterrey Knox Abbott are now closed and are working on their new location in the old Zeus Pizza location in Parkland Plaza (not Parklane Plaza). I believe this location started as a Denny's, though according to Monterrey's closing sign, they were here for 26 years, which is no small run for a restaurant.

Kids' exercise and gymnastics center The Little Gym has moved out of the suite on Beltline adjacent to the old Sulley's and over to the Sounds Familiar location on Rosewood. As of today, they are open:
